We synthesized a directed library of compounds to explore the structure-activity relationships of peroxisome proliferator-activated receptor δ(PPARδ) activation relative to mesenchymal stem cell (MSC) osteogenesis. Our scaffold used para-substituted cinnamic acids as a polar headgroup, a heteroatom and heterocycle core connecting units, and substituted phenyl groups for the lipophilic tail. Compounds were screened for their ability to increase osteogenesis in MSCs, and the most promising were examined for subunit specificity using a quantitative PPAR transactivation assay. Six compounds were selected for in vivo studies in an ovariectomized mouse model of human postmenopausal osteoporosis. Four compounds improved bone density in vivo, with two (12d and 31a) having activity comparable to that of GW0742, a well-studied PPARδ-selective agonist. 31a (2-methyl-4-[N-methyl-N-[5-methylene-4-methyl-2-[4-(trifluoromethyl)phenyl]thiazole]]aminocinnamic acid) had the highest selectivity for PPARδcompared to other subtypes, its selectivity far exceeding that of GW0742. Our results confirm that PPARδis a new drug target for possible treatment of osteoporosis via in situ manipulation of MSCs.

The free fatty acid receptor 1 (FFA1 or GPR40) and peroxisome proliferator-activated receptor δ (PPARδ) have attracted a lot of attention due to their role in promoting insulin secretion and sensibility, respectively, which are two major features of diabetes. Therefore, the dual FFA1/PPARδ agonists would increase insulin secretion and sensibility by FFA1 and PPARδ activation. In this study, we hybrid FFA1 agonist AM-4668 with PPARδ agonist GW501516, leading to the identification of orally bioavailable dual agonist 32, which revealed high selectivity over other PPARs. Moreover, compound 32 exhibited good pharmacokinetic profiles with high plasma concentration, sustained half-life and low clearance in vivo. During the hypoglycemic test, a dual agonist 32 enhanced the tolerance of ob/ob mice for glucose loading in a dose-dependent manner. Our results suggest that dual FFA1/PPARδ agonist could be a valuable therapy for type 2 diabetes.

The free fatty acid receptor 1 (FFA1/GPR40) has attracted interest as a novel target for the treatment of type 2 diabetes. Several series of FFA1 agonists including TAK-875, the most advanced compound terminated in phase III studies due to concerns about liver toxicity, have been hampered by relatively high molecular weight and lipophilicity. Aiming to develop potent FFA1 agonists with low risk of liver toxicity by decreasing the lipophilicity, the middle phenyl of TAK-875 was replaced by 11 polar five-membered heteroaromatics. Subsequently, systematic exploration of SAR and application of molecular modeling, leads to the identification of compound 44, which was an excellent FFA1 agonist with robustly hypoglycemic effect both in normal and type 2 diabetic mice, low risks of hypoglycemia and liver toxicity even at the twice molar dose of TAK-875. Meanwhile, two important findings were noted. First, the methyl group in our thiazole series occupied a small hydrophobic subpocket which had no interactions with TAK-875. Furthermore, the agonistic activity revealed a good correlation with the dihedral angle between thiazole core and the terminal benzene ring. These results promote the understanding of ligand-binding pocket and might help to design more promising FFA1 agonists.
